Abstract

The FPGA+DSP architecture has been widely used in spaceborne digital signal systems. In order to adapt to the complex space environment, reduce the impact of single-event flipping, and meet the on-orbit requirements of intelligence and high reliability, a spaceborne dual-core system is proposed. On-track betting method. Taking Fudan Micro JFM7 series JFM7K325T and TI's TMS320C6678 as examples, the hardware circuit design and software design of FPGA+DSP program on-rail injection are introduced in detail. The ground experiment verification proves that the on-rail injection method is reasonable and feasible, and improves the reliability of the system that can complete the remote fault repair and function expansion of the onboard software.
